Unplanned downtime in injection molding often stems from nozzle clogging, resulting in an average loss of hundreds of dollars per hour in production. A Michigan-based auto parts manufacturer reported losing over a dozen hours per month due to nozzle clogging, resulting in significant waste of production time. Nozzle clogging, caused by solidified molten plastic or… Continue reading Learn how to quickly solve molding machine nozzle clogging problems in 5 minutes

Unstable plasticization, inaccurate demolding, and excessively long production cycles lead to significant losses in production efficiency. On average, each factory loses tens of thousands of dollars annually due to PP material waste and failure to meet production targets. As product managers at Topstar, we’ve heard many clients raise these issues. One large home appliance brand… Continue reading Case Study: Injection Molding of Rice Cooker Shell Using a 260-Ton Injection Molding Machine

A 2024 survey found that 32% of production scrap and 18% of cycle time extensions in injection molding were attributed to poorly performing mold temperature controllers. In actual production, a water-type mold temperature controller operating with a 2°C deviation can reduce yield from 95% to 85% overnight. You can’t just set up a mold temperature… Continue reading 2025 Optimization Checklist: Methods to Improve the Performance of Any Mold Temperature Controller

Manufacturers across many regions lose 15% to 20% of their production time due to communication delays and parameter loss in traditional hydraulic or basic electric injection molding machines. For a 24/7 factory, this translates to 1,080 hours of wasted production annually and millions of dollars in lost revenue. Even worse, 4% to 8% of parts… Continue reading Digital Platform All Electric Injection Molding Machine: Enhance Efficiency & Parameter Control

Every year, many manufacturers waste 5-10% of their raw materials due to degradation, equivalent to significant resource losses for a medium-sized enterprise operating 24/7. Worse still, these manufacturers fail to realize that degradation is the root cause of part defects. As an injection molding machine manufacturer, I’ve found that 70% of degradation cases are due… Continue reading How can I prevent material degradation by adjusting the molding machine barrel temperature?

The global plastic water cup market produces over 50 billion units annually. For these manufacturers, every second of cycle time translates into real profit. Even a two-second reduction in production per cup can save hundreds of millions of dollars for a 24/7 factory. However, many water cup manufacturers report inefficiencies in their factories, such as… Continue reading 170ton injection molding machine: Water cup injection molding production

According to a survey by the Mobile Phone Accessories Market Report, 65% of US consumers prefer soft PU phone cases due to their superior feel, anti-slip properties, and shock absorption, making them one of the best-selling phone case types. However, many cases suffer from uneven softness, surface bubbles, or incomplete mold filling. One Indian customer… Continue reading How to successfully produce soft PU phone cases on a mobile cover making machine？

One customer we worked with told us they were previously rejecting 15% of their thick-walled battery casing batches due to warpage. This issue was resolved after they switched to a Topstar 120°C mould temperature controller. Now, they’ve achieved a 98% yield and reduced cycle time by 10%. In injection moulding, a deviation of just 0.5°C… Continue reading 120°C mould temperature controller: Which industries are suitable for 120°C

Inadequate monitoring of molding machine performance in injection molding production can lead to scrap, rework, and financial losses. As a Topstar injection molding machine user, you are responsible for your production results when using our machines. Therefore, we have leveraged our experience as a manufacturer to provide you with five performance indicators to track during… Continue reading 5 key performance indicators to track in molding machine production

A 90 ton injection molding machine offers low clamping force, yet its size is sufficient for processing a wide range of multi-cavity consumer product parts, miniature appliance housings, and structural components. It is often an ideal choice for parts with moderate projection areas and wall thicknesses, as well as mold designs that require a stable… Continue reading Under what circumstances can a 90 ton injection molding machine bring better molding results?

Many medical device recalls stem from component failures, which can often be traced back to inaccurate injection molding processes. For a client I work with that produces blood glucose meter panels, this risk is particularly acute. A dimensional deviation of even 0.1 mm can cause internal sensors to misalign, leading to inaccurate blood glucose readings… Continue reading Medical Injection Molding Case Study: Blood Glucose Meter Panel Production

Mid-sized injection molding plants lose tens, if not hundreds, of thousands of dollars annually due to flash—the thin, excess plastic that seeps through mold crevices. This translates into not only scrapped parts but also rework time to trim parts, premature mold wear, and rejected orders from quality-conscious customers. As a professional injection molding machine manufacturer,… Continue reading How to solve the problem of flash in injection molding?
